Stay away from that powmax piece of (goodlooking) crap.
The CoolerMaster PSU is a bit weak on the +12v rails, only 12+10=22Amp
It will do fine for your current PC, but as soon as you want to upgrade, you will be in trouble.
Look for something with at LEAST 16+16, better is 18+18, such as the ENERMAX Noisetaker EG495P-VE SFMA ATX 485W Power Supply
